This market will resolve according to the calendar date (ET) on which Google's next Gemini Pro model is made available to the general public. Any Gemini model released after market creation and labeled as "Pro" may qualify (e.g., gemini-3.2-pro, gemini-3.5-pro, or gemini-4.0-pro-preview). Gemini models labeled only as Flash, Flash-Lite, or another non-Pro variant will not qualify. Products labeled as a GA promotion of an already-existing Preview model (e.g., gemini-3.1-pro-ga) may qualify. A qualifying model must be launched and publicly accessible, including via open beta or open rolling waitlist signups. A closed beta or any form of private access will not suffice. The release must either be clearly defined and publicly announced by Google as accessible to the general public, or otherwise be made publicly accessible and explicitly labeled on the company's official website. Labeling errors, placeholder text, or version names displayed on the website that do not correspond to a model that is actually accessible to the general public will not qualify. The primary resolution source for this market will be official information from Google, with additional verification from a consensus of credible reporting.
Google’s repeated delays of the Gemini 3.5 Pro flagship, originally targeted for June and then July 2026, continue to shape trader views, with the model still described as under partner testing and “coming soon” in late-July updates. Recent releases have focused on lighter variants such as Gemini 3.7 Flash (generally available August 13) and earlier 3.6/3.5 Flash iterations, while training on Gemini 4 has already begun. No official September timeline or preview has emerged as of mid-August, and historical patterns of extended validation, safety reviews, and integration work reinforce the market’s 59% implied probability of no Pro release by September 30. Key upcoming catalysts include any Google I/O-style announcements or earnings commentary that could shift the window.
